REGULATOR-VALVE FOR GAS-BURNERS.

, To all whom it may concern for heating steam radiators and the like.

The object of this invention is to provide a regulator valve by means of which the supply of gas is regulated by the steam pressure and by means of which the supply of gas is automatically cut off when the steam pressure reaches a predetermined point. Y

Another object is to provide adjustment by which the amount of pressure necessary to cut off the gas supply maybe regulated.

Vith these objects in view the invention consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the vappended claims, it being understood that various changes in the form,. proportions, size and minor details of construction may be'made within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages ofthe invention.

In the accompanying drawings: Figure 1 is a fragmentary sectional view of a portion of a steam radiator and gas burner showing my improved regulator valve in connection therewith. Fig. 2 is-an enlarged sectional view of the regulator vvalve showing the turning valve in the proper position for lighting the burner. Fig. 3 is a similar view showing the turning lvalve in the safety7 position.

Similar numerals of reference indicate corresponding parts throughout the several figures of the drawings. l

Referring more especially to the construction illustrated in the accompanying drawings 1 represents the lower portion of the end section of a steam radiator and 2-2 represent the adjoining sections which are connectedin lany suitable and well known manner as by the rings 3 which allow communCatOn between .all Qf thectiees es Specification of Letters Patent.

shown. A thimble 4: is screw threaded into the section 1 and a small section of pipe 5 which is connected to the regulator valve is slidably vmounted within said thimble, extending'into the interior of the radiator at a point above thewater line, as shown in Fig. 1 of the drawing. The pipe 5 is connected by an elbow Gwith a short pipe 7 which is screw threaded into the neck 8 of the top 9 of the steam chamber casing. The body portion 10 of the steam chamber casing is provided with screw threads around its periphery by means of which van internally screw threaded cap 11 is connected thereto, said cap being provided with an inwardly disposed Y annular flange 12, which contacts with the shoulder 13 formed upon the top 9, clamping said top upon the body portion of the casing.

A flexible diaphragm 14, preferably composed of thin sheet metal is provided with the osetflange 15 which is seated between the shoulder 16 of the steam chamber casing and the Ytop 9, a gasket 17 preferably being interposed between said'ifiange 15 and the top for the purpose of making a steam, tight joint. i

A screw threaded extension 18 is provided upon the lower. extremity of the casing V10 to which is attachedV the portion To the portion 19 of thecasing'is attached a Vgas supply i pipe 20 by-means of a union or elbow 21 as shown; said elbow being connected vto the casing bv means of the screw threaded eX- tension 22. The supply pipe is connected to Y the casing by means of the screw threaded extension 22. The supply pipe is connected to any suitable source of supply such as street pipes properly connected to a gasometer or other source of supply, reference bev y ing had to the kind ofgas employed. A turn-valve 23 is located in the casing 19 and adapted to be operated bv means of a handle 241., said valve being for the purpose of shutting off the supply of gas to the valve when desired, and for setting the valve in the safety position as will be hereinafter described.

A spring chamberz is provided in the casing and a concentric cylindrical boref26 communicates therewith A needle valve 27 is located through the cylindrical bore 26 Y and is providedupon its upper extremity with a head 28 which bears against the diaphragm .14 .A horizental Partition 29 Yis provided within the casing 19 and extends from the side walls of said casing to the turn valve 23 dividing the casing into the upper and lower compartments 30 and 31 respectively. A spring 31 is interposed between the head 28 and the lower wall 32 of the spring chamber and tends to normally hold the needle valve in the position shown in Fig. 2. The conical collar 33 is adjustably mounted upon said needle valve bv means of a set screw or its equivalent 34, being seated within the conical aperture 35 formed in the partition 29. The lower extremity of the needle 27 is provided with the usual tapered portionV 36 adapted to engage the valve seat 37. the reduced aperture 38 leading from said valve seat to the chamber 39.

VA regulating needle valve 40, provided with a screw threaded portion 41 is located through the chamber 39, the screw threaded portion 41 being engaged by the internal screw threads 4t2 and a. stuffing box 43 being located around said screw threaded portion for the purpose of forming an air tight joint. The tapered extremity of the needle 40 is located within the valve seat 4&4: and the opposite end of said needle valve is provided with a souared head 45 by means of which the needle may be rotated for the purpose of regulating the low of gas therethrough.

An ordinary mixer 46 is connected upon the neck 47 in any suitable and well known manner and provided with the usual apertures 18 to allow the admission ot' air. A tube 49 is connected with the mixer and is connected with an ordinary Bunsen burner 50.

The operation of the device is as follows: llVhen it is desired to light the burner 50 the turn valve 23 is moved into the position shown in Fig. 2, allowing gas to pass from the supply pipe 20 through said turn valve and into the lower chamber 31 and then through the aperture 38 into the chamber 39 and thence into the burner 50. lVhen the stem pressure has become sufficient to expand the diaphragm 14 against the pressure of the spring 31y suliiciently to move the conical collar 33 carried upon the needle 27 out of engagement with the valve seat 35, the turn valve 23 may be moved into the position shown in Fig. 3 allowing the gas to pass fromthe supply pipe 20 through said turn valve and into the chamber 30 and thence through the aperture 35 to the chamber 31 through the aperture 33 to the chamloer 39 and thence to the burner. As the steam pressure increases to a point where it is necessary to lcut offthe burner the diaphragm 14 will be further expanded, seating the needle point 36 within the valverseat 37, thus shutting oii the supply of gas to the burner and causing the light in the pressure has been reduced, thus again mov`v ing the needle valve 27 in the position shown in said figure and allowing gas to escape to the burner. which is at this time extinguished. The object of this invention is to prevent accidents happening from circumstances such as the above.

Although the drawings and above speci iication disclose the best mode in which 1 have contemplated embodying my invention l 1 desire to be not limited to the details ot"-Y such disclosure, forin the further practical application of my invention, many changes 1n form and construction may be made, as circumstances require or experience suggests, without departing from the spirit of `the invention, within the scope of the appen ded claims.
